This 40-Pfennig commemorative from Deutsche Bundespost Berlin (1977) honors Eduard Gaertner (1801–1877), one of the finest German architectural painters of the 19th century. The stamp features a finely engraved portrait, showcasing classic line-dot intaglio work typical of Berlin issues of the era. Issued to mark the 100th anniversary of Gaertner’s death, it reflects the precision and elegance that echo his own artistic style—famed for Berlin cityscapes and Prussian architectural accuracy. Ideal for collectors of German portraiture, Berlin postal history, and art-themed philately.
